At its forward end the cam memberlS provided with a lifting cam 70 having a pair of elemovement in the head 12 of the machine is a lift ing bar 72,-the lower end of which bears against the cam 'lilandthus serves as a lifting block.-

Rivqted to the lifting bar 72 is a block 74 posi as thecam member 18 rotates, the lifting bar '72 is elevated by the cam 70, the spring 64 being correspondingly compressed. Then when-one ofv the elevated portions of the cam 70 passes out 0; from beneath thelower end of the lifting bar 72,-. the spring 64 forces the-lifting bar "22 and the lifting block '74 downwardly, thus rocking the lever I 62 in; ar--counterclockwise direction and forces the tool carrier-32 and the tool 30 downwardly. g A bumper 7.8 clamped on the upper end of thelifting bar 72 impinges'on a boss 80, thus limiting the downward strokeof the lifting bar '72. In the illustrated machine, one portion of the cam 72 passes out from beneath the lifting bar when the fulcrum- 60- of the lever 72 is in its uppermost position, the tool 30 then being forced downwardly through-a nozzle 82 i and into the ndimay e eaeea .shankr ce .tq be fastened;

The position of the link 46 may-also? Mounted for vertical. slidinginside a turn shoe. When the shaft 16 has been rotated through another 180 degrees and the other elevated portion of the cam 70 has raised the lifting bar '72 and passed out from beneath the lifting bar, the fulcrum 60 of the lever 62 has been moved to its lowermost position, so that the downward movement of the tool carrier 32 and thetool 30 -is only sufiicient to drive the fastening; which "atthat time has been; brought into alinement'with the'tliroatopening of the noazle 82 and with the tool 30. In order that 'thetwo strokes of the tool 30 though terminating at different points may be approximately of the same length, one elevated portion of the cam '70 is so n''ewhat higher: than the other elevated portion; 1

Themechanism' for countersinking or enlarging the entrance for the fastening receiving hole will now be described. Secured to the shaft 16 is-a cam86 (Figs. 1, 2, 3 and 4) which acts against a ,camroll 88 to move the arm 90 of a bell crank 1everf91in a clockwisedirection as viewed from the front of the machine in Figs. 3 and 4. The bell crank 91 is journaled' tothefmachine head by means of apin 92 (Fig. 4) and'the cam roller 88 is held against the cam86 by means of a suitable spring 94.. The lower arm of the bell crank 914s formedwith teeth 96 which mesh with teeth 98 formedon a collar 100 which in turn is clamped to one end of a shaft 102 by means of a stud 1 04. The shaft. 102 is journaled in a bearing "106 formed in the head of the machine. Formed at the other' end of the shaft 102 is a ,collar 108 having. teeth ,110 which mesh with teeth 112 secured toor formed'as a part of a sleeve carrying member 114 which carries at its lower end a sleeve 116.l The sleeve carrier 114 has at its upper end a tool" guide 117 through whichthe. tool30' passes and the sleeve carrier 114 and the sleeve 116 have a passage 118 through which the tool 30rciprocates.. Rotation of the shaftv 16 causes the. high part 87 of the cam 86 to swing the arm 91 in a clockwise direction which, through the connections above described, causes thesleeve 116 to be moved downwardly from the, position shown in Fig. 5 to the position shown Fig. 6 sothatthe conical lower end of the sleeve countersinksor"enlarges the entrance to the fastening receiving hole which has previouslybeen formed'by-the tool 30 and forms an enlarged entrance for a lfastening receiving hole; A fastening 122 is thereafter inserted and headed in the enlarged entrance to the hole as hereinafter described.

The paper twine fromwhich thefibre pegs inserted by the illustrated machine are out, is carried by a-reel- 128 (Fig.1) rotatably mountedupon the head 12 of the machine. The twine passes, from the reel 128 to a tubular guide memher 130 mounted for verticalreciprocating movement at the front of thehead of the machine.

Means for engaging the twine and feeding itdownwardly with the downward movement of the guide 130 and for preventing retrograde movement of the twine 126 is indicated generally by the numeral 132. The twine feeding and measuring mechanism is substantially as shown in the above-mentioned copending application Serial No. 202,416 to which reference may be had for a more detailed description of the twine feeding mechanism.
